(John Wiley & Sons, Inc., 1991)
The influence of the biexcitons formed from two orthoexcitons on the Bose-Einstein condensation (BEC) of orthoexcitons and the possibility of the BEC of biexcitons is studied theoretically. It is shown that the existence ...

(Elsevier, 2013)
The collective elementary excitations of two-dimensional magnetoexcitons in a Bose–Einstein condensate (BEC) with wave vector k→=0 were investigated in the framework of the Bogoliubov theory of quasi-averages. The Hamiltonian ...

(John Wiley & Sons, Inc., 1995)
The renormalization of the energetical spectrum of paraexcitons in the presence of a Bose-Einstein condensate (BEC) of orthoexcitons or at least of their saturation is studied. Due to the conversion of a pair of orthoexcitons ...

(John Wiley & Sons, Inc., 1985)
The quasiequilibrium state of the two-component non-linear ortho-para-exciton gas is investigated. The concentration shifts of the exciton levels are taken into account at high densities of quasiparticles. Three exciton ...
